Abstract

A filter arrangement includes an activated carbon filter, a fuel tank, an engine, at least one of an air filter or a dust filter, and at least one valve. The at least one valve is configured to allow fresh air to flow through the activated carbon filter in order to regenerate the carbon filter. The activated carbon filter is at least one of associated with the intake tract of the engine, integrated into the intake tract of the engine; or a component of a modular unit with the intake tract of the engine.

Claims

1. A filter arrangement comprising:

an activated carbon filter;

a fuel tank;

an engine;

at least one of an air filter or a dust filter; and

at least one valve,

wherein the at least one valve is configured to allow fresh air to flow through the activated carbon filter in order to regenerate the carbon filter, and

wherein the activated carbon filter is at least one of associated with the intake tract of the engine, integrated into the intake tract of the engine;

or a component of a modular unit with the intake tract of the engine.

2. The filter arrangement according to claim 1, wherein the air filter and the dust filter are combined to form a modular unit.

3. The filter arrangement according to claim 1, wherein the activated carbon filter is situated upstream from at least one of an intake manifold of the engine (15) or a turbocharger in such a way that fresh air flowing through at least one of the dust filter or through the air filter is conveyed into the activated carbon filter through at least one feed line or at least one diagnostic unit.

4. The filter arrangement according to claim 3, wherein a second feed line coming from the activated carbon filter opens up into a feed point of a fresh-air intake line of the turbocharger.

5. The filter arrangement according to claim 4, wherein a fresh-air main line coming from the air filter opens up from the air filter into the feed point.

6. The filter arrangement according to claim 3, wherein at least one of the first feed line can be opened and closed by a first feed line valve, the second feed line can be opened and closed by a second feed line valve, or the fresh-air main line can be opened and closed by a fresh-air main line valve.

7. The filter arrangement according to claim 4, wherein a mixing valve that regulates the composition of the fresh air flowing into the fresh-air intake line is arranged at the feed point.

8. The filter arrangement according to claim 1, wherein the activated carbon filter and the air filter are combined to form a modular unit.

9. The filter arrangement according to claim 1, wherein a fluid-carrying housing section is disposed upstream from at least one of an intake manifold of the engine or a turbocharger, wherein a valve that regulates the composition of the fresh air that is conveyed to at least one of the intake manifold or the turbocharger is integrated into the fluid carrying housing section, wherein the fresh air comprises a first air mass flow coming from the activated carbon filter and a second air mass flow coming from the air filter.

10. The filter arrangement according to claim 9, wherein the housing section opens up into at least one of the intake manifold or the turbocharger.

11. A method to optimize the regeneration of an activated carbon filter in a filter arrangement, the method comprising at least one of:

associating the activated carbon filter with at least one of an intake tract of an engine;

integrating the activated carbon filter into the intake tract of the engine;

or

forming a structural unit consisting of the engine and the activated carbon filter,

wherein the filter arrangement includes an activated carbon filter, a fuel tank, an engine, at least one of an air filter or a dust filter, and at least one valve, and

wherein the at least one valve is configured to allow fresh air to flow through the activated carbon filter in order to regenerate the carbon filter.
